Buried deep in a South African cave, 2.2 million-year-old teeth may hold the genetic signature of a mysterious human relative ...

Researchers have extracted 2 million-year-old protein remains from ancient pre-human teeth to reveal biological sex and ...

Scientists have successfully extracted ancient proteins from two-million-year-old teeth, a breakthrough providing previously unobtainable details on ...

Sloth size and habitat shifted multiple times over the past 35 million years, but human hunting likely drove the slower, ...

This manuscript introduces a useful protein-stability-based fitness model for simulating protein evolution and unifying non-neutral models of molecular evolution with phylogenetic models. The model is ...

Seed plants, such as soybeans, store large amounts of protein in specialized organelles called protein storage vacuoles.

The genomes of long-living, big-brained mammal species reveal that they carry more copies of immunity genes. Experts ...

Abstract: In bioinformatics, protein multiple sequence alignment (MSA) and phylogenetic tree construction are among the major problems for which many algorithms have been developed to improve the ...
